Amacrox Calmer 560: Silence is Golden

Internals Continued
The two coils on the right of the primary side are actually mounted on small PCBs and not directly on the main PCB. There is a heat conducting tape between the coils and the heatsink behind them to transfer the generated heat from the coil directly to the heatsink. The larger PCB on the left side contains the PFC control.
The main capacitor is rated at 105°C, which is obviously necessary since there is no fan to cool this part down. The capacitor comes from Panasonic rated at 470µF with 450V.
Things look quite cramped in this design, although with a lack of airflow all of the extra heatsinks and heat transfer surfaces make sense. The idea is to get all the heat conducting to external surfaces that should have some airflow from the rest of the system.
The secondary side features some Teapo and Ostor capacitors, all rated at 105° again since it will be somewhat hot inside the PSU.

Interesting concept though. I wonder how this will hold up with an 80mm fan?yyrkoon - Wednesday, April 2, 2008 - link
I use the Antec EarthWATTS 500 which also uses a 80mm fan, and i works fine. Matter of a fact the fan is barely audible most of the time.I do have do agree with the OP here though. At first I thought he/she was referring to the outside of the PSU, which I think does not look bad(except that ugly red button). The innards of this thing looks like it was put together by preschool children with construction paper, elmers glue . . . So . . . One cannot help but wonder if child labor is involved here.
They sent this thing out looking like it does(including the heat sink that looks like it was cut out of an aluminum block with a rock) knowing that you would take it apart ?

Well, since those heatsinks have to touch the external one, that is probably why they look like that, big and covered with thermal interface.
